    • Introduction

    IBM Watson™ Discovery is a cognitive search and content analytics engine that you can add to applications to identify patterns, trends and actionable insights to drive better decision-making. Securely unify structured and unstructured data with pre-enriched content, and use a simplified query language to eliminate the need for manual filtering of results.

    The IBM Watson Unity SDK has the following requirements.

    • The SDK requires Unity version 2018.2 or later to support Transport Layer Security (TLS) 1.2.
      • Set the project settings for both the Scripting Runtime Version and the Api Compatibility Level to .NET 4.x Equivalent.
      • For more information, see TLS 1.0 support.
    • The SDK doesn't support the WebGL projects. Change your build settings to any platform except WebGL.

    Authentication

    IBM Cloud Identity and Access Management (IAM) is the primary method to authenticate to the API. However, with some older service instances you authenticate with the username and password for the service instance.

    To find out which authentication to use, view the service credentials by clicking the service instance in the Resource list.

    • For service instances that use IAM authentication, you can pass either a bearer token in an authorization header or an API key. Tokens support authenticated requests without embedding service credentials in every call. API keys use basic authentication. For testing and development, you can pass an API key directly. However, for production use, unless you use the Watson SDKs, use an IAM token. For more information, see Authenticating to Watson services.

      If you pass in an API key, use apikey for the username and the value of the API key as the password. For example, if the API key is f5sAznhrKQyvBFFaZbtF60m5tzLbqWhyALQawBg5TjRI in the service credentials, include the credentials in your call like this:

        curl -u "apikey:f5sAznhrKQyvBFFaZbtF60m5tzLbqWhyALQawBg5TjRI"

    • In other instances, you authenticate with the username and password for the service instance. The "username" and "password" in the service credentials are different from your IBM Cloud account IBMid and password. For more information, see Authenticating with Cloud Foundry service credentials.

    The SDK provides initialization methods for each form of authentication.

    • For service instances that use IAM authentication, the SDK provides two initialization methods: one that accepts an API key and another that accepts an access token that is created from an API key.

      • Use the API key to have the SDK manage the lifecycle of the token. The SDK requests an access token, ensures that the access token is valid, and refreshes it if necessary.

      • Use the access token to manage the lifecycle yourself. You must periodically refresh the token.

        For more information, see IAM authentication with the SDK.For more information, see IAM authentication with the SDK.For more information, see IAM authentication with the SDK.For more information, see IAM authentication with the SDK.For more information, see IAM authentication with the SDK.For more information, see IAM authentication with the SDK.For more information, see IAM authentication with the SDK.For more information, see IAM authentication with the SDK.

    • For service instances that use username and password authentication, use the BasicAuthenticator initialization method and specify the username and password. For more information, see Authenticating with Cloud Foundry service credentials.

    Access between services

    You can grant access between your IBM Cloud services and to your services by applications that need it.

    • To grant access between IBM Cloud services, create an authorization between the services. For more information, see Granting access between services.
    • To grant access to your services by applications without using user credentials, create a service ID, add an API key, and assign access policies. For more information, see Creating and working with service IDs.

    For more information about IAM, see IAM access.

    To grant this access, use an endpoint URL that includes the service instance ID (for example, https://api.us-south.discovery.watson.cloud.ibm.com/instances/6bbda3b3-d572-45e1-8c54-22d6ed9e52c2). You can find the instance ID in two places:

    • By clicking the service instance row in the Resource list. The instance ID is the GUID in the details pane.

    • By clicking the name of the service instance in the list and looking at the credentials URL.

      If you don't see the instance ID in the URL, you can add new credentials from the Service credentials page.

    Service endpoint

    The service endpoint is based on the location of the service instance. For example, when Discovery is hosted in Washington DC, the base URL is https://api.us-east.discovery.watson.cloud.ibm.com. The URL might be different for instances that were created before 13 December 2019 or when you use IBM Cloud Dedicated.

    To find out which URL to use, view the service credentials by clicking the service instance in the Resource list. Use that URL in your requests to Discovery.

    Set the correct service URL by calling the setServiceUrl() method of the service instance.

    Set the correct service URL by calling the url parameter when you create the service instance.

    Set the correct service URL by calling the url parameter when you create the service instance or by calling the set_url() method of the service instance.

    Set the correct service URL by calling the url parameter when you create the service instance or by calling the url= method of the service instance.

    Set the correct service URL by the URL parameter when you create the service instance or by calling the SetURL= method of the service instance.

    Set the correct service URL by setting the serviceURL property of the service instance.

    Set the correct service URL by calling the SetEndpoint() method of the service instance.

    Set the correct service URL by setting the Url property of the service instance.

    Disabling SSL verification

    All Watson services use Secure Sockets Layer (SSL) (or Transport Layer Security (TLS)) for secure connections between the client and server. The connection is verified against the local certificate store to ensure authentication, integrity, and confidentiality.

    If you use a self-signed certificate, you need to disable SSL verification to make a successful connection.

    Enabling SSL verification is highly recommended. Disabling SSL jeopardizes the security of the connection and data. Disable SSL only if necessary, and take steps to enable SSL as soon as possible.

    To disable SSL verification for a curl request, use the --insecure (-k) option with the request.

    To disable SSL verification, create an HttpConfigOptions object and set the disableSslVerification property to true. Then, pass the object to the service instance by using the configureClient method.

    To disable SSL verification, set the disableSslVerification parameter to true when you create the service instance.

    To disable SSL verification, specify true on the set_disable_ssl_verification method for the service instance.

    To disable SSL verification, specify true on the configure_http_client method for the service instance.

    To disable SSL verification, call the DisableSSLVerification method on the service instance.

    To disable SSL verification, call the disableSSLVerification() method on the service instance. You cannot disable SSL verification on Linux.

    To disable SSL verification, set the DisableSslVerification method to true on the service instance.

    To disable SSL verification, set the DisableSslVerification method to true on the service instance.

    Example that disables SSL verification

    IAM authentication. Replace {apikey} and {url} with your service credentials.

    curl -k -u "apikey:{apikey}" -X {request_method} "{url}/{method}"

    Example that disables SSL verification

    IamAuthenticator authenticator = new IamAuthenticator("{apikey}");
Discovery discovery = new Discovery("{version}", authenticator);
discovery.setServiceUrl("{url}");

HttpConfigOptions configOptions = new HttpConfigOptions.Builder()
  .disableSslVerification(true)
  .build();
discovery.configureClient(configOptions);

    Example that disables SSL verification

    const DiscoveryV1 = require('ibm-watson/discovery/v1');
const { IamAuthenticator } = require('ibm-watson/auth');

const discovery = new DiscoveryV1({
  version: '{version}',
  authenticator: new IamAuthenticator({
    apikey: '{apikey}',
  }),
  url: '{url}',
  disableSslVerification: true,
});

    Example that disables SSL verification

discovery.disableSSLVerification()

    Example that disables SSL verification

    IamAuthenticator authenticator = new IamAuthenticator(
    apikey: "{apikey}"
    );

DiscoveryService discovery = new DiscoveryService("{version}", authenticator);
discovery.SetServiceUrl("{url}");

discovery.DisableSslVerification(true);

while (!authenticator.CanAuthenticate())
    yield return null;

var discovery = new DiscoveryService("{version}", authenticator);
discovery.SetServiceUrl("{url}");

discovery.DisableSslVerification = true;

    Versioning

    API requests require a version parameter that takes a date in the format version=YYYY-MM-DD. When we change the API in a backwards-incompatible way, we release a new version date.

    Send the version parameter with every API request. The service uses the API version for the date you specify, or the most recent version before that date. Don't default to the current date. Instead, specify a date that matches a version that is compatible with your app, and don't change it until your app is ready for a later version.

    Specify the version to use on API requests with the version parameter when you create the service instance. The service uses the API version for the date you specify, or the most recent version before that date. Don't default to the current date. Instead, specify a date that matches a version that is compatible with your app, and don't change it until your app is ready for a later version.

    This documentation describes the current version of Discovery, 2019-04-30. In some cases, differences in earlier versions are noted in the descriptions of parameters and response models.

    Error handling

    The Discovery service uses standard HTTP response codes to indicate whether a method completed successfully. HTTP response codes in the 2xx range indicate success. A response in the 4xx range is some sort of failure, and a response in the 5xx range usually indicates an internal system error that cannot be resolved by the user. Response codes are listed with the method.

    Data handling

    Additional headers

    Some Watson services accept special parameters in headers that are passed with the request.

    You can pass request header parameters in all requests or in a single request to the service.

    To pass a request header, use the --header (-H) option with a curl request.

    To pass header parameters with every request, use the setDefaultHeaders method of the service object. See Data collection for an example use of this method.

    To pass header parameters in a single request, use the addHeader method as a modifier on the request before you execute it.

    To pass header parameters with every request, specify the headers parameter when you create the service object. See Data collection for an example use of this method.

    To pass header parameters in a single request, use the headers method as a modifier on the request before you execute it.

    To pass header parameters with every request, specify the set_default_headers method of the service object. See Data collection for an example use of this method.

    To pass header parameters in a single request, include headers as a dict in the request.

    To pass header parameters with every request, specify the add_default_headers method of the service object. See Data collection for an example use of this method.

    To pass header parameters in a single request, specify the headers method as a chainable method in the request.

    To pass header parameters with every request, specify the SetDefaultHeaders method of the service object. See Data collection for an example use of this method.

    To pass header parameters in a single request, specify the Headers as a map in the request.

    To pass header parameters with every request, add them to the defaultHeaders property of the service object. See Data collection for an example use of this method.

    To pass header parameters in a single request, pass the headers parameter to the request method.

    To pass header parameters in a single request, use the WithHeader() method as a modifier on the request before you execute it.

    To pass header parameters in a single request, use the WithHeader() method as a modifier on the request before you execute it.

    Example header parameter in a request

    curl -u "apikey:{apikey}" -X {request_method} --header "Request-Header: {header_value}" "{url}/{method}"

    Example header parameter in a request

    ReturnType returnValue = discovery.methodName(parameters)
  .addHeader("Custom-Header", "{header_value}")
  .execute();

    Example header parameter in a request

    const parameters = {
  {parameters}
};

discovery.methodName(
  parameters,
  headers: {
    'Custom-Header': '{header_value}'
  })
   .then(result => {
    console.log(response);
  })
  .catch(err => {
    console.log('error:', err);
  });

    Example header parameter in a request

    response = discovery.methodName(
    parameters,
    headers = {
        'Custom-Header': '{header_value}'
    })

    Example header parameter in a request

    response = discovery.headers(
  "Custom-Header" => "{header_value}"
).methodName(parameters)

    Example header parameter in a request

    result, response, _ := discoveryv1.methodName(
  &methodOptions{
    Headers: map[string]string{
      "Accept": "application/json",
    },
  },
)

    Example header parameter in a request

    let customHeader: [String: String] = ["Custom-Header": "{header_value}"]
discovery.methodName(parameters, headers: customHeader) {
  response, error in
}

    Example header parameter in a request

    IamAuthenticator authenticator = new IamAuthenticator(
    apikey: "{apikey}"
    );

DiscoveryService discovery = new DiscoveryService("{version}", authenticator);
discovery.SetServiceUrl("{url}");

discovery.WithHeader("Custom-Header", "header_value");

    Example header parameter in a request

    var authenticator = new IamAuthenticator(
    apikey: "{apikey}"
);

while (!authenticator.CanAuthenticate())
    yield return null;

var discovery = new DiscoveryService("{version}", authenticator);
discovery.SetServiceUrl("{url}");

discovery.WithHeader("Custom-Header", "header_value");

    Response details

    The Discovery service might return information to the application in response headers.

    To access all response headers that the service returns, include the --include (-i) option with a curl request. To see detailed response data for the request, including request headers, response headers, and extra debugging information, include the --verbose (-v) option with the request.

    Example request to access response headers

    curl -u "apikey:{apikey}" -X {request_method} --include "{url}/{method}"

    To access information in the response headers, use one of the request methods that returns details with the response: executeWithDetails(), enqueueWithDetails(), or rxWithDetails(). These methods return a Response<T> object, where T is the expected response model. Use the getResult() method to access the response object for the method, and use the getHeaders() method to access information in response headers.

    Example request to access response headers

    Response<ReturnType> response = discovery.methodName(parameters)
  .executeWithDetails();
// Access response from methodName
ReturnType returnValue = response.getResult();
// Access information in response headers
Headers responseHeaders = response.getHeaders();

    All response data is available in the Response<T> object that is returned by each method. To access information in the response object, use the following properties.

    Property Description
    result Returns the response for the service-specific method.
    headers Returns the response header information.
    status Returns the HTTP status code.

    Example request to access response headers

    discovery.methodName(parameters)
  .then(response => {
    console.log(response.headers);
  })
  .catch(err => {
    console.log('error:', err);
  });

    The return value from all service methods is a DetailedResponse object. To access information in the result object or response headers, use the following methods.

    DetailedResponse

    Method Description
    get_result() Returns the response for the service-specific method.
    get_headers() Returns the response header information.
    get_status_code() Returns the HTTP status code.

    Example request to access response headers

    discovery.set_detailed_response(True)
response = discovery.methodName(parameters)
# Access response from methodName
print(json.dumps(response.get_result(), indent=2))
# Access information in response headers
print(response.get_headers())
# Access HTTP response status
print(response.get_status_code())

    The return value from all service methods is a DetailedResponse object. To access information in the response object, use the following properties.

    DetailedResponse

    Property Description
    result Returns the response for the service-specific method.
    headers Returns the response header information.
    status Returns the HTTP status code.

    Example request to access response headers

    response = discovery.methodName(parameters)
# Access response from methodName
print response.result
# Access information in response headers
print response.headers
# Access HTTP response status
print response.status

    The return value from all service methods is a DetailedResponse object. To access information in the response object or response headers, use the following methods.

    DetailedResponse

    Method Description
    GetResult() Returns the response for the service-specific method.
    GetHeaders() Returns the response header information.
    GetStatusCode() Returns the HTTP status code.

    Example request to access response headers

    import "github.com/IBM/go-sdk-core/core"
result, response, _ := discoveryv1.methodName(&methodOptions{})

// Access result
core.PrettyPrint(response.GetResult(), "Result ")

// Access response headers
core.PrettyPrint(response.GetHeaders(), "Headers ")

// Access status code
core.PrettyPrint(response.GetStatusCode(), "Status Code ")

    All response data is available in the WatsonResponse<T> object that is returned in each method's completionHandler.

    Example request to access response headers

    discovery.methodName(parameters) {
  response, error in

  guard let result = response?.result else {
    print(error?.localizedDescription ?? "unknown error")
    return
  }
  print(result) // The data returned by the service
  print(response?.statusCode)
  print(response?.headers)
}

    The response contains fields for response headers, response JSON, and the status code.

    DetailedResponse

    Property Description
    Result Returns the result for the service-specific method.
    Response Returns the raw JSON response for the service-specific method.
    Headers Returns the response header information.
    StatusCode Returns the HTTP status code.

    Example request to access response headers

    var results = discovery.MethodName(parameters);

var result = results.Result;            //  The result object
var responseHeaders = results.Headers;  //  The response headers
var responseJson = results.Response;    //  The raw response JSON
var statusCode = results.StatusCode;    //  The response status code

    The response contains fields for response headers, response JSON, and the status code.

    DetailedResponse

    Property Description
    Result Returns the result for the service-specific method.
    Response Returns the raw JSON response for the service-specific method.
    Headers Returns the response header information.
    StatusCode Returns the HTTP status code.

    Example request to access response headers

    private void Example()
{
    discovery.MethodName(Callback, Parameters);
}

private void Callback(DetailedResponse<ResponseType> response, IBMError error)
{
    var result = response.Result;                 //  The result object
    var responseHeaders = response.Headers;       //  The response headers
    var responseJson = reresponsesults.Response;  //  The raw response JSON
    var statusCode = response.StatusCode;         //  The response status code
}

    Data labels

    You can remove customer data if you associate the customer and the data when you send the information to a service. First, you label the data with a customer ID, and then you can delete the data by the ID.

    • Use the X-Watson-Metadata header to associate a customer ID with the data. By adding a customer ID to a request, you indicate that it contains data that belongs to that customer.

      Specify a random or generic string for the customer ID. Do not include personal data, such as an email address. Pass the string customer_id={id} as the argument of the header.

    • Use the Delete labeled data method to remove data that is associated with a customer ID.

    Labeling data is used only by methods that accept customer data. For more information about Discovery and labeling data, see Information security.

    For more information about how to pass headers, see Additional headers.

    Data collection

    By default, Discovery service instances that are not part of Premium plans log requests and their results. Logging is done only to improve the services for future users. The logged data is not shared or made public. Logging is disabled for services that are part of Premium plans.

    To prevent IBM usage of your data for an API request, set the X-Watson-Learning-Opt-Out header parameter to true.

    You must set the header on each request that you do not want IBM to access for general service improvements.

    You can set the header by using the setDefaultHeaders method of the service object.

    You can set the header by using the headers parameter when you create the service object.

    You can set the header by using the set_default_headers method of the service object.

    You can set the header by using the add_default_headers method of the service object.

    You can set the header by using the SetDefaultHeaders method of the service object.

    You can set the header by adding it to the defaultHeaders property of the service object.

    You can set the header by using the WithHeader() method of the service object.

    Example request

    curl -u "apikey:{apikey}" -H "X-Watson-Learning-Opt-Out: true" "{url}/{method}"

    Example request

    Map<String, String> headers = new HashMap<String, String>();
headers.put("X-Watson-Learning-Opt-Out", "true");

discovery.setDefaultHeaders(headers);

    Example request

    const DiscoveryV1 = require('ibm-watson/discovery/v1');
const { IamAuthenticator } = require('ibm-watson/auth');

const discovery = new DiscoveryV1({
  version: '{version}',
  authenticator: new IamAuthenticator({
    apikey: '{apikey}',
  }),
  url: '{url}',
  headers: {
    'X-Watson-Learning-Opt-Out': 'true'
  }
});

    Example request

    discovery.set_default_headers({'x-watson-learning-opt-out': "true"})

    Example request

    discovery.add_default_headers(headers: {"x-watson-learning-opt-out" => "true"})

    Example request

    import "net/http"

headers := http.Header{}
headers.Add("x-watson-learning-opt-out", "true")
discovery.SetDefaultHeaders(headers)

    Example request

    discovery.defaultHeaders["X-Watson-Learning-Opt-Out"] = "true"

    Example request

    IamAuthenticator authenticator = new IamAuthenticator(
    apikey: "{apikey}"
    );

DiscoveryService discovery = new DiscoveryService("{version}", authenticator);
discovery.SetServiceUrl("{url}");

discovery.WithHeader("X-Watson-Learning-Opt-Out", "true");

    Example request

    var authenticator = new IamAuthenticator(
    apikey: "{apikey}"
);

while (!authenticator.CanAuthenticate())
    yield return null;

var discovery = new DiscoveryService("{version}", authenticator);
discovery.SetServiceUrl("{url}");

discovery.WithHeader("X-Watson-Learning-Opt-Out", "true");

    Synchronous and asynchronous requests

    The Java SDK supports both synchronous (blocking) and asynchronous (non-blocking) execution of service methods. All service methods implement the ServiceCall interface.

    • To call a method synchronously, use the execute method of the ServiceCall interface. You can call the execute method directly from an instance of the service.
    • To call a method asynchronously, use the enqueue method of the ServiceCall interface to receive a callback when the response arrives. The ServiceCallback interface of the method's argument provides onResponse and onFailure methods that you override to handle the callback.

    The Ruby SDK supports both synchronous (blocking) and asynchronous (non-blocking) execution of service methods. All service methods implement the Concurrent::Async module. When you use the synchronous or asynchronous methods, an IVar object is returned. You access the DetailedResponse object by calling ivar_object.value.

    For more information about the Ivar object, see the IVar class docs.

    • To call a method synchronously, either call the method directly or use the .await chainable method of the Concurrent::Async module.

      Calling a method directly (without .await) returns a DetailedResponse object.

    • To call a method asynchronously, use the .async chainable method of the Concurrent::Async module.

    You can call the .await and .async methods directly from an instance of the service.

    Example synchronous request

    ReturnType returnValue = discovery.method(parameters).execute();

    Example asynchronous request

    discovery.method(parameters).enqueue(new ServiceCallback<ReturnType>() {
  @Override public void onResponse(ReturnType response) {
    . . .
  }
  @Override public void onFailure(Exception e) {
    . . .
  }
});

    Example synchronous request

    response = discovery.method_name(parameters)

    or

    response = discovery.await.method_name(parameters)

    Example asynchronous request

    response = discovery.async.method_name(parameters)
